# YoutubeIE PO Token Provider Framework
As part of the YouTube extractor, we have a framework for providing PO Tokens programmatically. This can be used by plugins.
Refer to the [PO Token Guide](https://github.com/yt-dlp/yt-dlp/wiki/PO-Token-Guide) for more information on PO Tokens.
> [!TIP]
> If publishing a PO Token Provider plugin to GitHub, add the [yt-dlp-pot-provider](https://github.com/topics/yt-dlp-pot-provider) topic to your repository to help users find it.
## Public APIs
- `yt_dlp.extractor.youtube.pot.cache`
- `yt_dlp.extractor.youtube.pot.provider`
- `yt_dlp.extractor.youtube.pot.utils`
Everything else is internal-only and no guarantees are made about the API stability.
> [!WARNING]
> We will try our best to maintain stability with the public APIs.
> However, due to the nature of extractors and YouTube, we may need to remove or change APIs in the future.
> If you are using these APIs outside yt-dlp plugins, please account for this by importing them safely.
## PO Token Provider
`yt_dlp.extractor.youtube.pot.provider`
```python
from yt_dlp.extractor.youtube.pot.provider import (
PoTokenRequest,
PoTokenContext,
PoTokenProvider,
PoTokenResponse,
PoTokenProviderError,
PoTokenProviderRejectedRequest,
register_provider,

```
## Logging Guidelines
- Use the `self.logger` object to log messages.
- When making HTTP requests or any other expensive operation, use `self.logger.info` to log a message to standard non-verbose output.
- This lets users know what is happening when a time-expensive operation is taking place.
- It is recommended to include the PO Token context and internal client name in the message if possible.
- For example, `self.logger.info(f'Requesting {request.context.value} PO Token for {request.internal_client_name} client from external provider')`.
- Use `self.logger.debug` to log a message to the verbose output (`--verbose`).
- For debugging information visible to users posting verbose logs.
- Try to not log too much, prefer using trace logging for detailed debug messages.
- Use `self.logger.trace` to log a message to the PO Token debug output (`--extractor-args "youtube:pot_trace=true"`).
- Log as much as you like here as needed for debugging your provider.
- Avoid logging PO Tokens or any sensitive information to debug or info output.
## Debugging
- Use `-v --extractor-args "youtube:pot_trace=true"` to enable PO Token debug output.
## Caching
> [!WARNING]
> The following describes more advance features that most users/developers will not need to use.
> [!IMPORTANT]
> yt-dlp currently has a built-in LRU Memory Cache Provider and a cache spec provider for WebPO Tokens.
> You should only need to implement cache providers if you want an external cache, or a cache spec if you are handling non-WebPO Tokens.
### Cache Providers
`yt_dlp.extractor.youtube.pot.cache`
```python
from yt_dlp.extractor.youtube.pot.cache import (
PoTokenCacheProvider,
register_preference,
register_provider
)
from yt_dlp.extractor.youtube.pot.provider import PoTokenRequest
@register_provider
class MyCacheProviderPCP(PoTokenCacheProvider): # Provider class name must end with "PCP"
PROVIDER_VERSION = '0.1.0'
# Define a unique display name for the provider
PROVIDER_NAME = 'my-cache-provider'
BUG_REPORT_LOCATION = 'https://issues.example.com/report'
def is_available(self) -> bool:
"""
Check if the provider is available (e.g. all required dependencies are available)
This is used to determine if the provider should be used and to provide debug information.
IMPORTANT: This method SHOULD NOT make any network requests or perform any expensive operations.

"""
return True
def get(self, key: str):
# ℹ️ Similar to PO Token Providers, Cache Providers and Cache Spec Providers
# are passed down extractor args matching key youtubepot-<PROVIDER_KEY>.
some_setting = self._configuration_arg('some_setting', default=['default_value'])[0]
return self.my_cache.get(key)
def store(self, key: str, value: str, expires_at: int):

# Cache entries should not be returned if they have expired.
self.my_cache.store(key, value, expires_at)
def delete(self, key: str):
self.my_cache.delete(key)
def close(self):
# Optional close hook, called when the YoutubeDL instance is closed.
pass
# If there are multiple PO Token Cache Providers available, you can
# define a preference function to increase/decrease the priority of providers.
# IMPORTANT: Providers should be in preference of cache lookup time.
# For example, a memory cache should have a higher preference than a disk cache.
# VERY IMPORTANT: yt-dlp has a built-in memory cache with a priority of 10000.
# Your cache provider should be lower than this.
@register_preference(MyCacheProviderPCP)
def my_cache_preference(provider: PoTokenCacheProvider, request: PoTokenRequest) -> int:
return 50
```
### Cache Specs
`yt_dlp.extractor.youtube.pot.cache`
These are used to provide information on how to cache a particular PO Token Request.
You might have a different cache spec for different kinds of PO Tokens.
```python
from yt_dlp.extractor.youtube.pot.cache import (
PoTokenCacheSpec,
PoTokenCacheSpecProvider,
CacheProviderWritePolicy,
register_spec,
)
from yt_dlp.utils import traverse_obj
from yt_dlp.extractor.youtube.pot.provider import PoTokenRequest
@register_spec
class MyCacheSpecProviderPCSP(PoTokenCacheSpecProvider): # Provider class name must end with "PCSP"
PROVIDER_VERSION = '0.1.0'
# Define a unique display name for the provider
PROVIDER_NAME = 'mycachespec'
BUG_REPORT_LOCATION = 'https://issues.example.com/report'
def generate_cache_spec(self, request: PoTokenRequest):
client_name = traverse_obj(request.innertube_context, ('client', 'clientName'))
if client_name != 'ANDROID':
# ℹ️ If the request is not supported by the cache spec, return None
return None
# Generate a cache spec for the request
return PoTokenCacheSpec(
# Key bindings to uniquely identify the request. These are used to generate a cache key.
key_bindings={
'client_name': client_name,
'content_binding': 'unique_content_binding',
'ip': traverse_obj(request.innertube_context, ('client', 'remoteHost')),
'source_address': request.request_source_address,
'proxy': request.request_proxy,
},
# Default Cache TTL in seconds
default_ttl=21600,
# Optional: Specify a write policy.
# WRITE_FIRST will write to the highest priority provider only,
# whereas WRITE_ALL will write to all providers.
# WRITE_FIRST may be useful if the PO Token is short-lived
# and there is no use writing to all providers.
write_policy=CacheProviderWritePolicy.WRITE_ALL,
)
